Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Difference in PIPR after a blue-light stimulus between the two groups; expressed in two parameters: - PIPR-mm = baseline pupil diameter (mm) * post-blue pupil diameter (mm) - PIPR-% = 100 x PIPR-mm/baseline pupil diameter (mm) | — |
Secondary
| Measure | Time frame |
|---|---|
| * Differences in questionnaire results on sleep quality, chronotype, fatigue and depression (MCTQ, HDSQ, PSQI, ESS, ISI, BQ, MFI-20, HADS) * Differences in polysomnography, actigraphy & sleep diary results * Differences in skin temperature results * Correlations between parameters of PIPR, sleep, sleep-wake rhythm and skin temperature | — |
